I am D-O-N-E with the
Great Date Callibre Project of Doom 
I had a number of books I
know I read back when I first purchased them in print that I had to guestimate dates for, but percentage wise it wasn't that many. I have read over 5000 books since 1989. (Not counting rereads). That total includes non-fiction. Not sure why I had started to keep track of the number of books I read every month, but I'm glad I kept it up over the years.
So now I have completed all of my wishlist projects (some of which I never even knew I wanted to do
). I have my Warehouse library with the name of the store(s) I purchased all of my books from with the untouched original versions of my books in case I ever need them. And my main Calibre library and the Vault library. My plan now is to always import new books to the Warehouse, clean-up the metadata as needed and then copy to either the main library or Vault. The only exception would be if it's a website freebie story (like Nalini Singh's slice-of-life newsletter stories or if an author posts an epilogue or deleted scenes on their wesbite of something) which I make an ePub from would go directly to the main library since they aren't from a store. I didn't add the various Silhouette/Harlequin on-line reads or the other Psy/Changeling short stories to the Warehouse either.
I know there are some books which I will probably clean-up in Edit Book when/if I reread them. But having done all of the Samhain titles, there are none I know have major issues.
My various library overhauls have taught me a lot. So even though they've been time consuming I am glad I've undertaken them all. But I'm ready to just be in maintenance mode and spend my time actually reading
Of course, I have to finish my taxes before I can start a new book, but I'm putting that off until tomorrow. (They're done, I just need to proof them. I'm not quite that bad of a procrastinator
)
I also dusted and rearranged all of my book shelves yesterday. Even though I'm not reading much in print nowadays, I still have my keepers. I should probably cull my print TBR pile since it keeps falling over when the dog bumps it, but that's a project for another day.
